Fine with me, though FWIW that not only doesn't use
__constant_cpu_to_le16() but actually swaps the non-constant value.

Don't see what point you are trying to make here. Swapping the value
from the actual command structure is always fine with me.

The point is that the result of swapping a constant value is just
another constant value, whereas the fix in mainline swaps a value from
memory. Not a big deal.

Surely, but surely, the definition of cpu_to_le16() uses
gcc 'magic' to determine that the argument is a constant
and then automatically selects the 'constant' form.
It can only do that if the argument is constant in the first place
though. :)
